IMPROVEM ENT IN UMBRELLA-RUNNERS.

Specification forming part of Letters Patent No. 212,428, dated February 18, 1879 application filed December 28, 1878.

To all whom it may concern:

Be it known that I, WILLIS H'. BELKNAP, of the city of New York, county and State of New York, have invented certain new and useful Improvements in Umbrella-Runners, of which the following is a specification:

This invention relates to umbrella-runners, and has for its object to lessen the cost of manufacture and to reduce the size of the notched fiange in which the ends ofthe stretchers are held to a minimum, thereby preventing any injury to the covering material by the dan ge, and allowing the umbrella to be folded in a smaller compass 5 but to describe my invention more particularly, I will refer to the accompanying drawings, forming part of t-his specification, in which- Figure l is a perspective View of my improved umbrella-runner. Fig. 2 is a longitudinal section of the same. Fig. 3 is a sectional view of the main tube; and Fig. 4 is a sectional view of short outside tube.

The main tube a, which is the slide or body of the runner, is made of thin metal, and is formed at one end, as shown at al, by means of forming-dies or by spinning. It is flared outward and then folded back onto itself, so as to form a flange of two thicknesses of metal, the original end of the tube being thrown down onto the body of the tube forming the bottom of the groove a4, in which the wire for holding the stretchers in the notches b b is placed, thus forming the upper half of the notched ange, as clearly shown at Fig. 3, and at Fig. 4 is shown how the lower half of the notched flange c is formed on the end of a short piece of tube, cthat is, by first Haring out one end of it and then folding` down said flare outwardly' onto itself. The tube c is made of thin metal, similar to tube c, but is of such a size as just to t over the tube c, as seen at Figs. l and 2, and the two parts when so placed are secured together by solder or other suitable means, and the notches b b cut through the two parts of the flange.

The slot a2 admits of the springs in the stick retaining the runner in place as ordinarily. The bottom of the main tube a is stiffened by the ring a3, secured thereon, or by being bent round onto itself after the short tube c is fastened in its place.

I am aware that umbrella-runners have been heretofore Inade by combining together separate pieces of wrought metal to form the notched rings in place of cast-metal ones; but by the combination of the two 4pieces of thin metal tube, formed up as before set forth and shown, I am enabled 'to greatly reduce the cost of manufacture and size of said articles; and

I claim- In an umbrella-runner, the tube a, spun or drawn up at one end, so as to form tulle upper VILLIS H. BELKNAP.
